At home my internet is slow because TimeWarner sucks, and i cant get anything else where i live, unless i want to pay for business class. Business Class 15x2 cost $250/mo and I have residential 10x1 right now for $55/mo so i was thinking that i could order two more lines of residential service.

The reason i need more speed is cause i want to use MozyPro and backup my FileServer (14TB) online. Well with 1.5mbps up it might take a while.

1) Do you think they will let me have more than one highspeed service on the same account? or multiple accounts for same address?
2) If I use like PFsense or something similar will i be able to load balance my outgoing connections and use the full bandwith?

Probably not, but you'd have to call and ask.

Not to Mozy, your load balancing will be route based (most likely) which means that to/from a destination it's going to use the same path. Good for multiple destinations but not for a single endpoint.

If you're looking to back up 14TB :eek: you may not have a good option- I know you can seed your backups (they send you an external drive, you send it back) but that's for maybe 1-2TB. I don't know what kind of data you have but I find it unlikely that ALL that needs to be backed up online, especially since I know that you're a Data-storage guru and have RAID arrays coming out of your ears. :)

Are you looking at backing all of that up? Wouldn't that be ~$7k a month?

I refer them a lot of business so i have a better deal;) Dont worry about the storage i got that covered, i just need a way to get it there

At least in pfSense you can load balance per-connection, not per host pair. If Mozy can generate multiple connections to the service then you can distribute the load across multiple links this way. Though I hardly see the point, 2x1.5mbit is just as unusable for backing up 14TB as 1x1.5mbit.

However, first of all you can generally only have one residential service per address, at least in my experience. Secondly, you might run into some issues if you do manage to get multiple services since it's fairly likely they will both end up with addresses on the same subnet. If that's the case you'll need a router between one of them and pfSense to do NAT there.

Maybe you can use p2p software to upload it to them. :p (seeing as you have good relations with them) That would use both connection i believe????
 
Could you have them send you external drives for the initial backup and then do incremental builds via your WAN?
 
The quote is typically attributed to Tenenbaum (I attribute it to him):

"Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway."

Consider the idea that burning a CD tends to work 7-8x as fast as a decent upstream connection to a broadband provider (assuming roughly 1MB/sec. on the broadband connection vs. 7.2MB/sec @ 48x CD write speed.) How long do you think it would take to burn all that data to 700MB CD's?

...well here's a very rough (and highly estimated) answer: 31531 minutes, or 525 hours, or ~21.9 days. Now, multiply by ~7.4 (assuming 100% uptime and continuous 1MB/sec connection, which is pretty good consistency) and that comes out to 162 days (heavily rounded, as stated before.)

So is your plan to not use your internet connection for the next ~5.5 months while you upload all of this data to a website for archiving/storage purposes?

Math wins again. :p:rolleyes::D And this is crappy, mildly-inaccurate math... try getting the exact figures and I think they'll be worse, not better, since I did round in your favor!

I can i was just hoping to make it all an automated process.
I dont care if it takes 3 months but at the rate i add thing it would take too long to ever get to a 100% so drives may be my only option.
 
we do that amount of transfer... except we have load-balanced point-to-point OC-3s... :p
 
No thats an idea!!

Do you think i could rent bandwith at a colo for like an three hours?

Pay like $300
 
Some colos might entertain that idea, pricing will probably vary wildly though. If you're lucky enough to live in Chicago, Dallas, LA or another major peering point you can probably find someone willing to let you in their data centre to chew bandwidth for a week, but it'll probably cost you a fair amount. Remember that 14TB @ a full 100mbit will take 13 days to transfer. At 1000mbit 1 day, 7 hours. And that's assuming you can actually maintain those speeds to Mozy, which I figure is unlikely.

I have a client on a full 100mbit symmetrical connection that uses an online backup service (can't remember which) and they can barely sustain 10mbit to it.

Aren't you making the assumption that both the host location AND the destination location will be able to support sufficient speeds to do what you want? Sending 4TB of data in an hour requires you to transmit an average of 1111.11MB/sec... even gigabit connections can't support this (especially since I'm using bytes, not bits, in the rounded calculations.)

I don't think you are being realistic with regard to the size of the numbers you want to work with, and the timeframes you'd like to achieve. You need to recognize the size of your numbers, and also recognize why such transmission speeds aren't yet available to the masses. Also, you may want to calcluate the amount of new content you generate, and whether or not your current bandwidth would be capable of supporting the backup of your new content. If you are unable to back up at a sufficient speed to keep up with your existing demand (and not even your legacy demand, which is your initial backup set) then this project is doomed to fail before it begins.
 
It would probably be a lot cheaper/quicker to buy a tape drive and then store the tapes off-site in the long-term.

Or buy some spare hard drives and do the same... I don't like the idea of a random 3rd party having access to my data (personal or otherwise).

I just pulled those numbers out my ass.
I mean i was looking at a colo here in dallas and they have a 5u/20Mbps unlimited package for $730/mo
even at 10 I would get it done in half the month.
(14 terabytes) / (10 MBps) = 16.9908148 days
 
You're conflating mbit and MB/s. 14TB @ 20mbit will take a little over 2 months.

...and he didn't take in to account that Mozy likely won't allow a high-speed connection to their servers. They pay for bandwidth too and they'll likely lock you down to 100KB or something like that, as they do with all customers.

A connection requires two sides--even if your side can fire off 100000MB/sec if the other side can only receive 0.25MB/sec that's the speed you'll be going at (but on the bright side you'll have a ton of extra bandwidth you aren't using!)

I realize that but i dont think they dont limit their business customers to 100kbs.
Hell on their "Home" service it can pull my entire 1.5 mbps
